Since November 30, SeaWorld Orlando has experienced a penguin chick boom. Fifteen penguin chicks have hatched at their new exhibit, Antarctica, Empire of the Penguin, which features four different species of penguin: king, Adelie, Gentoo, and rockhopper.

From SeaWorld Orlando:

Although currently ranging in size from 6 inches to 21 inches, the king chick, the largest penguin at SeaWorld’s Antarctica will grow to be as tall as 2.5 ft. and its smallest, the rock hopper will grow to be approximately 12 inches tall.

On November 30, SeaWorld Orlando welcomed the first chick to hatch at their new attraction, Antarctica: Empire of the Penguin. The two-week old king penguin chick weighs 882 grams (30 oz.). It is being cared for by its parents with routine checkups from SeaWorld Orlando staff. The little chick will grow to more than 11 kilograms (24 lbs.) and over 2.5 feet tall.

Like emperor penguins, king penguins do not build nests. Instead the mother and father take turns incubating the egg under their belly on top of their feet.

An extremely rare all-black penguin was photographed near Antartica by Andrew Evans of National Geographic. The king penguin doesn’t look like his tuxedoed counterparts because of what one scientist described as a “one in a zillion kind of mutation.”
